Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4114R-2-103 is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ
• Tolerance: ±2%
• Number of resistors: 13
• Circuit configuration: Bussed
• Power per element: 125mW
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 125°C
• Package: 14-DIP (0.300", 7.62mm)
• Pin count: 14
• Mounting: Through Hole
• Resistor-ratio-drift: 50ppm/°C

The 4114R-2-103LF meets all electrical and mechanical parameters required for direct substitution. Differences in RoHS compliance status and HTSUS classification do not affect functional or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 4114R-2-103 and 4114R-2-103LF are active production parts from Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements:

• 4114R-2-103: Select for applications where RoHS non-compliant components are acceptable or required by design specifications.
• 4114R-2-103LF: Select for applications requiring ROHS3 compliance. This variant is the preferred choice for new designs and applications subject to RoHS regulations.

Both parts are suitable for through-hole PCB assembly in the 14-DIP package format and support the full operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the 4114R-2-103LF replace the 4114R-2-103 in existing designs?

A: Yes. The 4114R-2-103LF is electrically and mechanically equivalent. It features identical resistance value, tolerance, power rating, temperature coefficient, and 14-DIP package dimensions. The primary difference is RoHS3 compliance status.

Q: Are there any pin configuration differences between these parts?

A: No. Both parts have 14 pins in identical DIP configuration with the same bussed resistor network topology.

Q: What is the significance of the "LF" suffix in the part number?

A: The "LF" designation indicates lead-free and RoHS3 compliance. This affects material composition and soldering requirements but does not change electrical performance or package compatibility.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts use the same 14-DIP through-hole package with identical footprint dimensions (0.765" L x 0.300" W, 19.43mm x 7.62mm) and maximum seated height (0.185", 4.69mm).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching resistance value (10kΩ), tolerance (±2%), number of resistors (13), circuit type (bussed), power per element (125mW), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 125°C), and package type (14-DIP).
